Hello everyone.Will the next who knows how to import multiple DEM data and matching satellite images?Terrain about 200km * 200Km, I want to use crome to make the terrain and import unity.I am ready to buy crome but I do not know how to deal with, I need your help. Thank you very much.

These show how to use multiple terrain zones, optimize them and export them to Unity via collada Grome plugin. Data is created in Grome but you can import them from satellite sources (as described bellow).

Digital elevation model data can imported in Grome using existing plugins: DTED, raw, geotiff etc. DTED and geotiff support real-world data that can be positioned based on geographical projections. Then you can import satellite images from geotiff that match perfectly these heightmaps.

Grome then can be used to manipulate and modify this data (if necessary you can increase resolutions, add details etc). 200km by 200km terrain can be supported since you can use the special Grome swap mechanism (the editor allows you to have in memory only a portion of the map, the one you work on). You can also automate much of the process using Grome scripting and manually edit only small parts when needed.

At export to Unity you can save the terrain zones as collada and in Unity editor re-assemble these into a continuous terrain using special Unity scripts we've developed (and presented in the tutorials above).

I hope this information helps. Let us know if you need additional support.

Thanks for your reply!
This is great support large terrain data. I have read your website and unity tutorial. I actually hands-on testing that it is really good!
But I use unity4.1.2.f1 test, it was found a few problems. May be because you is a tutorial material is created in version 3.x, unity automatically updated when switching model
When wrong. Open the scene in Unity mountain lost mesh grid data, but the problem can be easily repaired. Regenerate the import model grid can
. Another problem is that I found the tutorial inside a script program to mesh Add TerrainLOD objects (by special characters traverse the object name - "_node)
Upgrade 4.x version of Unity, model data into the scene view neutron object to be renamed, this time would not be able to find with _node labeled objects, so it needs a script from
Automatically added "_node mark.

There is also a doubt Unity With LODGroup components, we can go directly to you? This is described in detail in the Unity documentation, so I think this tutorial needs more
New look. Of course, this is my personal opinion.

You just said in reply to some other software can easily convert the format to the production of software you use, if you can, can you help me write a small tutorial (some simple screenshot)? I downloaded you

You have software demo version, do not know how to import. Because I am not familiar with. I think the other person is not familiar with the same need, thanks very much for this!

There is software you do very good, but the user may untiy not know much about, you can go to the untiy Forum publicity, I hope you will do better!

(I'm sorry, my native language is not English, so you look in some places may be a little strange, huh, huh.) Thanks again for your prompt reply!

Thank you for pointing out that there are some issues with the new Unity 4 version. We will have a look over this and update the tutorials in the future. Also if you decide to purchase Grome we will help you with the update of the scripts to Unity 4 version.

Grome demo doesn't have the SDK in it so you cannot export and import. The SDK is present only in the full version of Grome (otherwise you would be able to just create your own save / load on the demo version). If you need more information about the import / export plugins please contact me (licu at quadsoftware.com is my direct email address or just send an email to the main contact emails from the site).

Yes, we've been to Unity forums. Some of the unity users are aware of Grome. Probably, as we will add new features in the future, we will announce them on the forums too.
